We have a lot of enumerations; by declaring fields as such, we make it
easier when debugging, since the debugger can display the enumerations
in cleartext. However, make sure exceptional values (like -1) are
included in the enumeration, since the compiler otherwise may not
include it in the valid range of the enumeration.
Implement "REL" and "ABS" modifiers for offsets in 64-bit mode. This
replaces "rip+XXX" type addressing. The infrastructure to set the default
mode is there, but there is nothing to throw the switch just yet.
Get rid of magic open-coded register numbers. We now keep track of
a total of three different kinds of register numbers: the register
enumeration (regs.h), the x86 register value, and the register flags.
That has all the information we need.
Additionally, do massive revamping of the EA generation code and the
REX generation logic.
64-bit support for ndisasm. This is very much an initial attempt, and
there are guaranteed to be bugs in the code. However, some *very*
preliminary testing seems to indicate it's not completely off-base.
64-bit support required some major changes to regs.dat; clean some of
it up (re-introduce patterns, where appropriate) and allow a single
register to belong to multiple disassembly classes; also keep track
of the x86 register number again.
Apparently configure was generating config.h, and nothing ever actually
included it. Include it in nasm.h as well as compiler.h, and in
rdoff/rdlar.h which uses these macros.
There appears to be no use of HAVE_* macros in any file that doesn't
have nasm.h included; in fact, so far the only use has been in
rdoff/rdlar.h.
a) Automatically generate dependencies for all Makefiles;
b) Move register definitions to a separate .dat file;
c) Add support for "unimplemented but there in theory" registers.
